CVE-2025-11569 is a vulnerability identified in the cross-zip software, a tool commonly used for handling ZIP archive files across multiple platforms. The vulnerability is characterized by a CVSS 4.0 vector of AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P, indicating that it is remotely exploitable over the network without requiring any authentication or user interaction. The primary impact is a high confidentiality breach, meaning an attacker can potentially access sensitive data processed or stored by cross-zip without altering the data's integrity or affecting system availability. The lack of required privileges and user interaction lowers the barrier for exploitation, increasing the risk profile. No specific affected versions are listed, and no patches or known exploits are currently documented, suggesting the vulnerability is newly published and may not yet be widely exploited. The vulnerability's exploitability and impact suggest it could be leveraged in targeted attacks to exfiltrate confidential information from systems using cross-zip, especially in environments where this software is integrated into automated workflows or backend services. The absence of integrity or availability impact means the attacker’s goal is primarily data theft rather than disruption or data manipulation. The vulnerability’s publication date is October 10, 2025, and it is assigned by the Snyk team. Organizations relying on cross-zip should be aware of this vulnerability and prepare to apply patches once available or implement compensating controls to mitigate risk.

For European organizations, the primary impact of CVE-2025-11569 is the potential unauthorized disclosure of sensitive information handled by cross-zip. This could affect sectors such as finance, healthcare, government, and technology where ZIP archives are used to transfer or store confidential data. The vulnerability’s remote exploitability without authentication means attackers could target exposed services or systems running cross-zip over the network, increasing the risk of data breaches. Loss of confidentiality can lead to regulatory penalties under GDPR, reputational damage, and financial losses. Since integrity and availability are not impacted, operational disruption is less likely, but the exposure of sensitive data alone is a critical concern. The lack of known exploits in the wild currently provides a window for proactive defense, but the ease of exploitation suggests attackers may develop exploits soon. European organizations with automated data processing pipelines or cloud environments using cross-zip are particularly vulnerable. The impact is heightened in countries with large IT infrastructures and critical industries that rely heavily on secure data handling.

1. Monitor official cross-zip repositories and vendor communications closely for patches or security advisories related to CVE-2025-11569 and apply updates promptly once available. 2. Restrict network access to systems running cross-zip by implementing firewall rules and network segmentation to limit exposure to untrusted networks. 3. Employ intrusion detection and prevention systems (IDS/IPS) to detect anomalous network activity targeting cross-zip services. 4. Conduct thorough vulnerability scanning and penetration testing focused on cross-zip implementations within the environment to identify potential exposure. 5. Review and harden configurations of cross-zip usage, ensuring it is not unnecessarily exposed to the internet or untrusted networks. 6. Implement data encryption at rest and in transit for ZIP archives to reduce the impact of confidentiality breaches. 7. Train security teams to recognize signs of exploitation attempts and establish incident response plans specific to data exfiltration scenarios. 8. Consider deploying application-layer gateways or proxies that can inspect and filter ZIP archive traffic to detect malicious payloads or unauthorized access attempts.
